Abstract
An arrangement of elements which are used to restrain and deflect a pipe specimen to a prescribed form with precisely controlled loads. A rigid frame includes a movable pipe bending form to which one end of a pipe specimen is connected and a rotating table to which the second end of the pipe specimen is connected. Means for assessing the drive torque used to draw the pipe specimen over the pipe bending form is provided in the form of a load cell. The rotating table is used in combination with a travelling pipe end truck foundation to generate a bending moment in the pipe specimen in the same plane as the pipe specimen is being bent by the pipe bending form. By the use of precise loads on the pipe specimen, computer analysis of the simulated reeling of the given pipe construction will produce predictions of the reeling tension, shear, and bending moment in the pipe at the point of the travelling pipe end as this point on the pipe approaches contact with the reel.
Description
Technical field
The present invention generally relates to the curling of pipe, and relates more specifically to manage curling load simulator.
Background technology
Up to now, in pipe stample fiber process, only have limited device to be used for testting the performance of given steel pipeline structure assembly.The assembly of testting the normally jam welding of the single carbon steel pipe by having or do not have certain class elastic coating fetches the pipe adapter of combination, or inside also is surrounded by the sort of carbon steel pipe of corrosion resisting alloy (CRA) or is called as the double-wall pipe assembly of " tube-in-tube ".The test specimen of testting this class pipeline structure is suitable for testting its intermediate tube assembly test specimen by the simple bending that comprises that the mode that the pipe stample fiber is installed is installed to prove it:
* apply single shear-type load by the free end at test specimen and be bent at the steel building mortion, be drawn as the shape consistent with building mortion so that be fixed on the test specimen of this building mortion base portion thus;
* apply single shear-type load by each end at test specimen and be bent at the steel building mortion; Perhaps
* come crooked with simple or 4 relative shear load-up conditions at 3.
Useful reality is managed curling container and is carried out comprehensive test.Yet this comprehensive test needs a large amount of sample tube and the time-consuming operation of the special container of the pipeline constructing apparatus that is used for spooling.
The curling of steel pipe structure comprises that the steel wall with pipe bends to the plastic zone.Being used at present that predicting is curled and entering the performance of pipe structure of plastic limit and analysis and the numerical approach of residue globality is approximate value.This is because the plastic property of pipe structure is by the real material attribute, accurately scantling and the collective effect that is difficult to precise figures ground or analyzes modeled border, ground loading condition are controlled in curly course.
In any structural load in linear (nonplastic) scope, the path of strain regime and load and sequence independence.In any non-linear plastic problem, the state of stress and strain is path and the order that highly depends on to reach the deformation pattern of required state.Therefore, when bending to plastic limit, the order that load is applied to structure is subjected to the impact of performance.
In order to make the physics test provide the meaning result, the test device must as far as possible accurately copy the contemplated actual working state of test.The prior art that test is exposed to the pipe structure of the curling strain of pipe can't accurately be replicated in actual axial tension and moment of flexure and the shearing that produces in the pipe stample fiber process.The out of true of actual loading state represents to cause to managing the wrong experimental judgment of structural behavior.In pipeline that execution is spooled structure Project Process, the mistake test judges and causes unpredictable loss, causes planning to incur loss through delay, coml and possible actual loss.
Therefore, can see to have the actual industrial of critically simulating pipe crimping to process to allow to verify the test device of the design that the curling pipeline of wanting is constructed.
Summary of the invention
The present invention solves the demand and proposes to be used to and will manage the arrangements of elements that test specimen limited and be deflected into reservation shape by precisely controlled load.Rigid frame comprises the movable pipe bendedwork pieces that is connected with pipe test specimen one end and the rotary work-table that is connected with pipe test specimen the second end.Form with dynamometer provides to estimate at the dilatory device of managing the employed driving moment of test specimen of pipe bendedwork pieces.Rotary work-table is used in combination to produce moment of flexure at same plane in the pipe test specimen when the pipe test specimen is managed the bendedwork pieces bending with the tube end vehicle seat seat of advancing.When arriving and contact with reel, predicts in curling pulling force, shearing and the moment of flexure at this some place the point that will be created in the tube end of advancing of pipe to the curling Computer Analysis of simulation of fixed tube structure.The pulling force of these predictions, shearing and moment of flexure can then be applied on the test specimen by the present invention, and test specimen reaction under these conditions is observed, measure and contrast with Computer Analysis.
In appended claims, specifically note various inventive features of the present invention and form a part of the present invention.In order to understand better the present invention and to use attainable its service advantages by it, with reference to the accompanying drawing and the description that form a part of the present invention, preferred embodiment of the present invention shown in it.
